Exercise bicycle

ABSTRACT

An exercise bicycle comprises a bicycle main body. The bicycle main body is provided with two elliptical wheels, wherein the front and the rear wheels are either arranged in parallel to each other, or arranged perpendicularly to each other. When the elliptical wheels are arranged in parallel to each other, the elliptical wheels are synchronously driven such that the rider will alternately rise up and fall down during the riding operations. Meanwhile, the shock absorber under the seat cushion also rises up and falls down. Whereas, when the elliptical wheels are arranged perpendicularly to each other, the elliptical wheels are perpendicularly driven such that the rider will move wavily during the riding operations. Regardless of arrangement of the elliptical wheels, during the riding operations, the rider can feel a riding-horse effect so as to enhance riding amusement and provide a whole body exercising effect to the rider.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to an exercise bicycle, and in particular, to anexercise bicycle capable of providing a whole body exercising effect andenhancing riding amusement to the rider.

2. Description of the Prior Art

Bicycles played important roles on our societies. In Taiwan, forexample, the social modes changed from an agricultural generation to anindustrial generation and toward a commercial generation. Bicycles wereused as means of transport in the early stages. Nowadays, withincreasing development of technologies, bicycles are also used as meansof leisure and exercise. On the other hand, bicycles were previouslymade cumbersome, thick and solid. However, today's bicycles are lightand streamlined and have various shapes for complying with differentpurposes, such as mountain bicycles, road bicycles, long-distancebicycles, foldable bicycles, etc. Furthermore, in views of environmentalprotection and health care, bicycles attract most people because nofuels are required and thus no pollutants are generated. However, anyforms of bicycles are monotonous and conservative. When the conventionalbicycles are used for the exercise and leisure purpose, only the feet ofthe riders are exercisable. In other words, the conventional bicyclesfail to provide the whole body exercising effect to the riders.

Accordingly, the above-described prior art product is not a perfectdesign and has still many disadvantages to be solved.

In views of the above-described disadvantages resulted from theconventional product, the applicant keeps on carving unflaggingly todevelop an exercise bicycle according to the present invention throughwholehearted experience and research.

SUMMARY OF THE INVENTION

An object of the invention is to provide an exercise bicycle capable ofproviding a whole body exercising effect to the rider.

Another object of the invention is to provide an exercise bicyclecapable of enhancing riding amusement to the rider.

Another still object of the invention is to provide an exercise bicyclecapable of providing a riding-horse effect.

Another still object of the invention is to provide an exercise bicyclehaving advantages of simple structure, easy operation, etc.

The above objects of the present invention can be achieved by using anexercise bicycle. The exercise bicycle comprises a bicycle main body. Ashock absorber is provided under the seat cushion of the bicycle mainbody. The bicycle main body is also provided with two elliptical wheels,wherein the front and the rear wheels are either arranged in parallel toeach other, or arranged perpendicularly to each other. When theelliptical wheels are arranged in parallel to each other, the ellipticalwheels are synchronously driven such that the rider will alternatelyrise up and fall down during the riding operations. Meanwhile, the shockabsorber under the seat cushion also rises up and falls down. Whereas,when the elliptical wheels are arranged perpendicularly to each other,the elliptical wheels are perpendicularly driven such that the riderwill move wavily during the riding operations. Meanwhile, the shockabsorber under the seat cushion will swing increasingly. During theriding operations, in case of emergence, the rider can tread on thefootrests in reverse direction so as to stop the bicycle. Regardless ofarrangement of the elliptical wheels, during the riding operations, therider can feel a riding-horse effect so as to enhance riding amusementand provide a whole body exercising effect to the rider. Furthermore,the shock absorber under the seat cushion is advantageous for increasingcomfort to the rider.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 2 is a schematic view illustrating an exercise bicycle according anembodiment of the present invention, wherein the elliptical wheelsthereof are arranged in parallel with each other;

FIG. 3 is a schematic view illustrating an exercise bicycle provided bythe present invention, wherein the elliptical wheels thereof arearranged perpendicularly to each other; and

FIG. 4 is a schematic view illustrating an exercise bicycle anembodiment of the present invention, wherein the elliptical wheelsthereof are arranged perpendicularly to each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 3, which are schematic views illustrating anexercise bicycle provided by the present invention, wherein theelliptical wheels thereof are either arranged in parallel andperpendicularly to each other, respectively. The exercise bicyclecomprises a bicycle main body 1. A shock absorber 12 is provided underthe seat cushion 11 of the bicycle main body 1, wherein the shockabsorber 12 is formed of a spring. The bicycle main body 1 is alsoprovided with two elliptical wheels 13, wherein the front and the rearwheels 13 are either arranged in parallel to each other, or arrangedperpendicularly to each other.

Referring to FIGS. 2 and 4, which are schematic views illustrating anexercise bicycle provided by the present invention, wherein theelliptical wheels thereof are either arranged in parallel andperpendicularly to each other, respectively. When the elliptical wheels13 are arranged in parallel to each other, the elliptical wheels 13 aresynchronously driven such that the rider will alternately rise up andfall down during the riding operations. Meanwhile, the shock absorber 12under the seat cushion 11 also rises up and falls down. Whereas, whenthe elliptical wheels 13 are arranged perpendicularly to each other, theelliptical wheels 13 are perpendicularly driven such that the rider willmove wavily during the riding operations. Meanwhile, the shock absorber12 under the seat cushion 11 will swing increasingly. During the ridingoperations, in case of emergence, the rider can tread on the footrests14 in reverse direction so as to stop the bicycle. Regardless ofarrangement of the elliptical wheels 13, during the riding operations,the rider requires strenuous effort to drive the elliptical wheels 13when the elliptical wheels 13 are arranged in parallel with each other.The driven elliptical wheels 13 are then arranged perpendicularly toeach other and spontaneously overturned forward due to such arrangement.Therefore, a relatively larger force and a relatively smaller force arealternately required for riding this bicycle, and the rider can feel awhole body exercising effect and a riding-horse effect due to therising-up/falling-down and wavily moving states, which can enhanceriding amusement to the rider. Furthermore, the shock absorber 12 underthe seat cushion 11 is advantageous for increasing comfort to the rider.

The above-mentioned main body of the exercise bicycle can be a main bodyof an electrical fuel bicycle or other bicycles using fuels such asgasoline, natural gas, solar power, etc. The specific arrangement of theelliptical wheels can largely enhance riding amusement to the rider.

The exercise bicycle provided by the present invention, when comparingwith other previous conventional technologies, has following advantages:

-   -   1. The specific arrangement of the elliptical wheels can provide        a whole body exercising effect to the rider.    -   2. The specific arrangement of the elliptical wheels can largely        enhance riding amusement to the rider.    -   3. The specific arrangement of the elliptical wheels can provide        a riding-horse effect to the rider.

Many changes and modifications in the above described embodiment of theinvention can, of course, be carried out without departing from thescope thereof. Accordingly, to promote the progress in science and theuseful arts, the invention is disclosed and is intended to be limitedonly by the scope of the appended claims.
